Abstract

The invention belongs to the technical field of fastening pieces, in particular to a self-locking bolt. The self-locking bolt comprises a first bolt, an elastic module and a second bolt; a first thread hole and a second thread hole are formed in the first bolt; the first thread hole is positioned in the first bolt; the second thread hole is positioned at the lower end of the first bolt; the firstbolt is an external hexagonal bolt; the elastic module is positioned at the middle part of the first bolt; the elastic module adopts a material of spring steel; the elastic module is one part of the first bolt; the first bolt is used for bolt self-locking; the second bolt is an internal hexagonal bolt, and is fixed in the first bolt through the first thread hole; the lower end of the second bolt is contacted with the upper end of the elastic module; and the second bolt is used for extruding the elastic module.

Description

technical field [0001] The invention belongs to the technical field of fasteners, in particular to a self-locking bolt. Background technique [0002] Fasteners composed of bolts and nuts are widely used in the connection of parts in machine tools, automobiles, agricultural machinery and other mechanical products. Due to their inherent defects, standard threads often loosen by themselves under severe vibration conditions, resulting in the connection The looseness of parts can cause the loss of the function of the machinery and equipment, and even lead to safety accidents. The existing methods for solving the loosening of threaded fasteners mainly include the following: inlaying nylon or elastic locking pieces, wearing anti-return pins, and installing anti-retraction elastic pads. The above methods generally have the defects of poor anti-loosening effect, complicated manufacturing or assembly process, high use cost and poor reusability. [0003] Patent document 1: A self-loc...
